HVAC · AC REPAIR & SERVICE
No cool air on a 32°C afternoon? We handle same-day no-cool emergencies across the GTA. Refrigerant top-ups, capacitor and contactor failures, frozen coils, drainage issues, seasonal tune-ups — all major brands. We diagnose with gauges and a meter, not a sales script. No fake "you need a new compressor" upsells: if it's a $40 capacitor, we tell you it's a $40 capacitor.
Most AC failures fall into a short list of common causes. We carry the parts and the gauges to fix them on the first visit — and we're not afraid to tell you when a repair is a better call than a replacement.
Tripped breaker, failed capacitor, blocked condenser coil, dirty filter, or restricted return air. We trace the actual root cause instead of guessing.
Almost always low refrigerant charge or restricted airflow. We thaw safely, find the underlying cause, and fix it — not just top up the gas and walk away.
Electronic leak detection and UV dye. R-22 is phased out and expensive — for older systems we'll talk you through a proper R-410A retrofit vs. replacement.
The #1 cause of "AC stopped working." A failed start/run capacitor or pitted contactor is a 30-minute fix — and the most-faked diagnosis in the trade.
Dead batteries, miswired C-wire, failed sensors, or a thermostat that's just plain misreading. Often the cheapest fix on the list — we check it first.
Water pooling around the air handler or a safety float shutting the system off mid-cycle. We clear the line, flush the trap, and verify the float switch operates.
Every "you need a new system" sales pitch starts with skipping the diagnostic. Here's the order we actually work in — and what each step is supposed to find.
What's the customer actually experiencing — no cool, weak cool, short cycles, noises? When does it happen? On startup, after 20 minutes, only in afternoon heat? Context narrows the search before any tool comes out.
Gauges on the high and low side, thermocouples on the suction and liquid lines. We calculate superheat and subcooling against the manufacturer's charging chart — that's how you know if the refrigerant charge is actually correct.
Measure capacitor MFD against rated value, verify contactor pull-in voltage, clamp the fan and compressor motor amps, inspect coil cleanliness and fin condition. Most "dead AC" calls end here, on a $40 part.
Fix it — most repairs land under $300. Recommend replacement only if the system is clearly past it (failed compressor on a 15-year-old R-22 unit, for example). Or schedule a follow-up if a slow leak needs more time to confirm.
An annual spring tune-up sounds like a sales pitch until you look at what actually fails on these systems. Four reasons it's worth the visit.
A summer's worth of cottonwood, dust, and grass clippings on the condenser coil drops capacity hard. Cleaning pays itself back the same season in lower hydro bills.
A weak capacitor will limp through April and die under load on the first real heat wave. A spring MFD test catches it before you're waiting two days for a service call.
Most leaks are small enough that you won't notice for a season or two — but they damage the compressor as the charge drops. Annual pressure checks catch them while they're cheap.
Most manufacturers (Lennox, Carrier, Trane, Goodman) require documented annual service to keep the parts warranty valid. Skip it and you're paying out of pocket when something goes.
